Man is born with certain rights. If this is unacceptable to some, it is because the recognition of this fact would interfere with their designs on their fellows.
An honest person will understand this after reading Ayn Rand's books.
"Man is born with certain rights."
Why? What are they? Is this not just a belief system, for which others could be substituted? What is the ultimate source of these "rights"? It seems hard to come up with an authoritative source without invoking God, an entity in which Rand did not believe. I think some of it is innate in the human psyche - concepts of "fairness" and "right and wrong" seem to be hardwired into our brains. From what I understand studies of behaviour of certain other primates, chimps in particular, seem to indicate a rudimentary understanding of such concepts in them - for example, "If you don't share with me, why should I share with you?" It's an interesting subject, to be sure. I imagine philosophers through time have pondered this very question - I wish I had studied more philosophy. Hey, whaddya know, philosophy may have something useful to tell us after all. What did Rand have to say on the subject? I assume she couldn't have been completely ignorant of this shortcoming in her philosophy of Objectivism.
